71407980 ÷ 391 
We want to divide 71407980 by 391.

Let's proceed to step 1:
391 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (1) from the dividend, attach it to 7 and continue: 71 / 391

Moving on to step 2:
391 goes into 71 0 times with a remainder of 71.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Fetch the next digit (4) from the dividend, attach it to 71 and continue: 714 / 391

Going ahead to step 3:
If we divide 714 by 391, we get 1 and a remainder of 323.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 391 from 714 leaves us with 323.
Bring next digit (0) of the dividend behind the 323 and repeat the process: 3230 / 391

Advancing to step 4:
391 goes into 3230 8 times with a remainder of 102.
Put 8 as the next digit of the answer. 
Result so far: 18.0
If we take 3128 away from 3230, we end up with 102.
Fetch the next digit (7) from the dividend, attach it to 102 and continue: 1027 / 391

Going ahead to step 5:
391 goes into 1027 2 times with a remainder of 245.
Record the quotient 2 as the next digit in the result. 
Result so far: 182.0
The remainder is 245 after subtracting 782 from 1027.
Grab the next digit (9) from the dividend, add it to 245, then carry on: 2459 / 391

Let's proceed to step 6:
The number 391 fits into 2459 6 times, leaving a remainder of 113.
Record the quotient 6 as the next digit in the result. 
Result so far: 1826.0
If we subtract 2346 from 2459, we get 113.
Append the next digit (8) from the dividend to 113 and continue with: 1138 / 391

On to step 7:
The number 391 fits into 1138 2 times, leaving a remainder of 356.
Use 2 as the next digit of our solution. 
Result so far: 18262.0
If we subtract 782 from 1138, we get 356.
Take the next digit (0) from the dividend and append it to 356, then repeat: 3560 / 391

Going ahead to step 8:
391 can be fit into 3560 9 times, resulting in a remainder of 41.
Put 9 as the next digit of the answer. 
Result so far: 182629.0
If we take 3519 away from 3560, we end up with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 9:
391 goes into 410 1 times with a remainder of 19.
The next digit of our result is 1. 
Result so far: 182629.1
Deduct 391 from 410 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 10:
190 divided by 391 is 0 with a remainder of 190.
The next digit of our result is 0. 
Result so far: 182629.1
If we take 0 away from 190, we end up with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Let's proceed to step 11:
When dividing 1900 by 391, we get 4 with a remainder of 336.
Put 4 as the next digit of the answer. 
Result so far: 182629.104
Deduct 1564 from 1900 and we're left with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

On to step 12:
391 goes into 3360 8 times with a remainder of 232.
The next digit of our result is 8. 
Result so far: 182629.1048
If we subtract 3128 from 3360, we get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Moving on to step 13:
2320 divided by 391 is 5 with a remainder of 365.
Record the quotient 5 as the next digit in the result. 
Result so far: 182629.10485
If we take 1955 away from 2320, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Step 14:
391 goes into 3650 9 times with a remainder of 131.
Put 9 as the next digit of the answer. 
Result so far: 182629.104859
If we take 3519 away from 3650, we end up with 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Step 15:
If we divide 1310 by 391, we get 3 and a remainder of 137.
Use 3 as the next digit of our solution. 
Result so far: 182629.1048593
Subtract 1173 from 1310 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 16:
When dividing 1370 by 391, we get 3 with a remainder of 197.
Record the quotient 3 as the next digit in the result. 
Result so far: 182629.10485933
The remainder is 197 after subtracting 1173 from 1370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1970, and continue the process.

After the division, we end up with 182629.10485933 and a remainder of 1.97e-07.
